Public preview of Azure Virtual WAN

Now a days networking trends such as SDWAN (Software-Defined Wide Area Network) uses to improve performance by using path selection polices at the branch offices to send Internet-bound traffic directly to the cloud eliminating the backhaul to select breakout points.

With the use of intelligent routing this traffic can quickly reach Microsoft’s global backbone network to provide the best network experience. By using this we tend to use all network branches. But in this technology we are facing a problem which is managing branch connectivity and uniformly enforcing network and security polices at scale, and complicating network policy management across all the branch offices is the trend of more employees working remotely with ever stricter security, privacy, and compliance requirements polices that vary by country/region.

Network security is an important aspect in protecting users, data and applications. Network teams and developers struggle to stay ahead of security attacks. Cloud native network security solutions better fit the modern dev ops model of building and deploying applications while taking advantage of the economic and scale benefits of the cloud. Customers need turnkey solutions that are easy to deploy, use, and manage that offer high availability and automatically scale.

To Overcome with these issues Microsoft has announced Azure Virtual WAN to simplify large-scale branch connectivity on cloud.

How it Works:
The new Azure Virtual WAN service provides optimized, automated and global scale branch connectivity. Virtual WAN brings the ability to seamlessly connect your branches to Azure with SDWAN & VPN devices (i.e. Customer Premises Equipment or CPE) with built in ease of use and    automated connectivity and configuration management.  

Virtual WAN is supported by Microsoft’s global network by using networking experience.When your traffic comes from branches Microsoft’s network at the Microsoft edge site closest to a given branch office. Microsoft has over 130 edge sites or Points of Presence (PoPs). When the traffic comes to Microsoft global network, it terminates in a virtual hub.

Available Regions and Partners:
Azure WAN contains multiple virtual hubs and you can create your own hubs in different azure regions. Azure has more global regions than any other public cloud provider bringing your virtual hubs close to your branches around the world.
Currently Microsoft is launching Azure Virtual WAN Preview with Citrix and Riverbed. And it will provide a fully automated branch connectivity experience. Solutions from additional partners such as Checkpoint, Nokia Nuage, Palo Alto and Silverpeak will be available in soon.

What it Brings:
Virtual WAN and virtual hubs: You can create a virtual WAN and then deploy virtual hubs in any Azure public region. This allows your hubs to be close to your branch offices. The hubs are where network traffic initially terminates before heading to another branch office or an Azure Virtual Network (VNet).
Connectivity automation: It is difficult to manually establish and manage a large number of VPN tunnels. Azure Virtual WAN brings together your preferred CPE be it SD-WAN controller or VPN device to automate the branch provisioning, configuration management and connectivity setup enabling you to easily deploy and manage your Virtual WAN. 
Automated VNet configuration: The automated VNet configuration allows you to easily connect your VNet to your hub so users in a branch office can access their Azure resources. 
Troubleshooting and monitoring: The platform monitors your on-premises connections providing a unified experience to manage your Virtual WAN along with your Azure resources.
